SLOW QUERIES
Current long_query_time = 10 sec.
You have 237 out of 523173 that take longer than 10 sec. to complete
The slow query log is NOT enabled.
Your long_query_time may be too high, I typically set this under 5 sec.



MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 1
Historic max_used_connections = 8
The number of used connections is 1% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See "MEMORY USAGE" section to make sure you are not over-allocating

MEMORY USAGE
Max Memory Ever Allocated : 101 M
Configured Max Per-thread Buffers : 2 G
Configured Max Global Buffers : 58 M
Configured Max Memory Limit : 2 G
Physical Memory : 978.82 M

Max memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 7 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 623
Key buffer fill ratio = 34.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 26 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 81.34 %
Current query_cache_min_res_unit = 4 K
Query Cache is 5 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.
However, 3657 queries have been removed from the query cache due to lack of memory
Perhaps you should raise query_cache_size
MySQL won't cache query results that are larger than query_cache_limit in size



JOINS
Current join_buffer_size = 1.00 M
You have had 80 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.


TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 10314 temp tables, 83% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.

You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform

consider setting 'concurrent_insert=2'.

Historic max_used_connections = 236
The number of used connections is 47% of the configured maximum.
Your max_connections variable seems to be fine.

MEMORY USAGE
Max Memory Ever Allocated : 1 G
Configured Max Per-thread Buffers : 1 G
Configured Max Global Buffers : 810 M
Configured Max Memory Limit : 2 G
Physical Memory : 1.97 G

Max memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 742 M
Current key_buffer_size = 768 M
Key cache miss rate is 1 : 992
Key buffer fill ratio = 10.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 24 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 76.29 %
Current query_cache_min_res_unit = 4 K
Query Cache is 16 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current record/read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 132.00 K
You have had 19734 queries where a join could not use an index properly
You have had 20 joins without keys that check for key usage after each row
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.

OPEN FILES LIMIT
Current open_files_limit = 2500 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_cache value = 512 tables
You have a total of 7120 tables
You have 512 open tables.
Current table_cache hit rate is 0%, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 2925987 temp tables, 3% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 128 K
Current table scan ratio = 403 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 3140
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
